abstract={Power transformer has an important role in the distribution of electric power systems. So, the transformer must be able to operate properly and can be used continuously in accordance with a predetermined time period. One that affects the condition of the transformer is the heat arising from loading and ambient temperature. The purpose of this study was to compare the effect of loading and ambient temperature on the age loss on two 60 MVA power transformers. To do
the calculations using loading data in 2019 unit 2 and unit 3 transformers obtained from PT.PLN (Persero) UP2B Jakarta and Banten also GIS PIK. The ambient temperature data uses North Jakarta's average temperature of 32.3°C. Based on the analysis, it can be concluded that the greater the load given to the
transformer, the shrinkage value of the age will be greater and the transformer age will be increasingly reduced. Transformer 2 has the largest age loss in September and October at 0.0418 p.u with an estimated remaining life span of 20.472 years while the largest shrinkage age of transformer 3 in November
amounted to 0.0286 p.u with an estimated remaining age of 20,523 years. So that the constant age shrinkage does not exceed 100% and the hot spot temperature is 98°C, then the load on the transformer must not exceed 91.41% or 54.846 MVA.}
